REED-ORGAN.

SPECIFICATION forming part; of Letters Patent No. 300,777, dated June 24-, 1884.

Application filed November 2, 1881.

1' 0 all whom it WMLZ/ concern:

Be it known that I, JACOB I-InssLnR, of Chicago, Cook county, State of Illinois, have i11- vented certain new and useful Improvements vers, and F the supportingblock composing the coupler; G, the key-supporting frame, and

None of these parts, in themselves and separately considered are here claimed as new.

Instead of building up from the socketboard separate supports for the front swell and the couplers, I place upon the. socketboard a longitudinal strip, I, which is made to serve four distinct functions. In the first place it supports the front swell; in the sec ond, it supports also the couplers; in the third, it serves as a lateral bearing for the upper end of the push-pins; and, lastly, iticloses the gaping mouths of the pin-openings in the socketboard. The drawing illustrates all these functions of the strip I very clearly.

In reed-organs as now constructed the pinopening through the socket-board is a tapering opening, with its largest diameter at the top, the bottom fitting the pin as closely as (No model.)

may be without creating friction. This leaves an open receptaclesurrounding the pin where dust or dirt accumulates, and from which receptacle the dirt soon works itsway down, creating friction between the pins and socket board, and lodging in the valves below, and so interfering with the operation of the pins and valves as to cause serious annoyance. To remedy this evil is the fourth function ascribed to the strip I, which I call the pi11-rail,and it is accomplished by making the rail to closely encircle each of the pins with atapc-red open ing the reverse of that in the socket-board, and by placing the rail directly upon the socket-board, instead of elevating it abovethe same, so as to leave an intervening longitudi nal open space in the usual manner. By this new construction each pin is provided with a close socket, which exerts the minimum of friction thereon, and prevents the usual hissing common to most organs, caused by the drawing into the pin-opening of the air from said intervening open space and the accumulation of dust therein.

The openings, instead of being tapered, as shown, may be of larger diameter than the pins, except at the top and bottom, if that is found to be a cheaper way of manufacture.

I claim as my invention The combination of the pins, the socketboard, and the pin-rail, said board and rail being provided with an independent close and reversely-tapered socket for each of the pins, substantially as specified.

JACOB IIESSLER.
